You can import workflows created external to Workflow Manager, or save and import to
another WFM View instance any workflows you create within WFM. You can import workflows
from within HDFS or from a local file system.

Prerequisite

If you are importing a workflow that was created external to Workflow Manager, ensure
that the workflow definition is valid. Workflows created in Workflow Manager are
validated, but there is no validation for externally-created workflows. Therefore,
Workflow Manager does not provide an error message for an invalid external workflow, nor
will an invalid workflow display in the workspace.

Important

If you import an existing workflow XML file, any comments in the file will be
lost.

Steps

Click Create > Workflow.

A new workspace displays with a basic workflow graph.

Click the workspace Workflow menu and do one of the following.

Import from the Hadoop file system:

Click Import from Shared File
System.

Navigate to the directory that contains the workflow
definition file that you want, click on the directory name,
and expand the directory.

Verify that a workflow.xml definition
file exists in the directory.

Tip

Do not click on the file name. The import action
must be performed at the directory level.

Verify that the directory you want is displayed in the
Selected Path field.

Click Select.

Import from your local file system:

Click Import from Local FS.

Navigate to the local directory that contains the
workflow.xml definition file that
you want and open the file.

The workflow graph displays in the workspace.

Tip

If the workflow definition is invalid, it does not display in the
workspace, and no error message is provided.
